An organisation seriously involved in the software business needs a tool based SCM system. There are numerous SCM tools of several tool vendors on the market at the moment. However, buying a tool is never the only solution to configuration management problems in an organisation. In practice it is best for an organization to choose the most suitable tool, and build the rest to get an effective SCM system. The SCM tool selection needs to be based on defining the software product management process, noticing the software engineering environments (SEEs) and the possibilities to add incremental components on the top of an SCM tool.
